Managing State in Flutter Pragmatically

By: RAHUL AGARWAL, Waleed Arshad

Overview of this book

Flutter is a cross-platform user interface (UI) toolkit that enables developers to create beautiful native applications for mobile, desktop, and the web with a single codebase. State management in Flutter is one of the most crucial and complex topics within Flutter, with a wide array of approaches available that can make it easy to get lost due to information overload. Managing State in Flutter Pragmatically is a definitive guide to starting out with Flutter and learning about state management, helping developers with some experience of state management to choose the most appropriate solutions and techniques to use. The book takes a hands-on approach and begins by covering the basics of Flutter state management before exploring how to build and manipulate a shopping cart app using popular approaches such as BLoC/Cubit, Provider, MobX, and Riverpod. Throughout the book, you'll also learn how to adopt approaches from React such as Redux and all its types. By the end of this Flutter book, you'll have gained a holistic view of all the state management approaches in Flutter, and learned which approach is the best solution for managing state in your app development journey.

Chapter 5: Executing Distinctive Approaches Like GetX, GetIt, and Binder

In the previous chapter, we studied state management approaches adopted from the React framework, which included Redux and MobX.

In this chapter, we will discuss some distinctive state management approaches that are relatively simpler, easier, and require less understanding of the underlying architecture. We will learn about GetX, GetIt, and Binder to manage states in Flutter. We will also look at how these approaches are utilized in code with actual implementations. We will look into the following in this chapter:

  • GetX – simplified reactive approach
  • GetIt – no BuildContext required
  • Binder – separation of concerns

This chapter is going to build up your understanding of how these distinctive approaches can be used to detect and track the changes inside a Flutter application. By the end of this chapter, you should be able to do the following:

  • Understand how...
